PREFACE. 


The  only  complete  collection  of  meteorological  tables  is  that  of  Guyotr 
first  published  by  the  Smithsonian  Institution  in  1852.  This  has  been 
enlarged  in  successive  revisions  until  the  212  pages  of  the  original  work 
have  grown  to  738  in  the  fourth  edition,  forming  a  very  valuable  compi- 
lation of  all  the  more  important  meteorological  and  physical  tables  in  use 
since  1850.  This  last  edition  leaves  nothing  to  be  desired  from  a  historical 
stand-point,  but  the  working  meteorologist  still  lacks  a  collection  of  the 
best  tables,  in  compact  form,  convenient  for  use,  and  at  small  cost.  The 
tables  now  presented  have  been  in  constant  use  by  the  author,  and  their 
present  form  is  the  result  of  many  years'  experience  in  the  application  of 
various  tables.  They  are  published,  not  to  supersede  the  earlier  and  more 
extended  collection,  but  as  a  convenient  hand-book. 

In  the  general  plan  of  the  work,  the  main  points  to  be  noted  are  as 
follows : 

1.  As  far  as  possible,  all  tables  relating  to  the  same  subject  are  placed 
together. 

2.  All  similar  tables  are  united.     Thus,  the  three  tables  for  convert- 
ing  millimetres   to   inches,  on  pp.  200,  225    and  258   of   Guyot1   form 
Table  XXXII  of  this  collection.     In  addition  to  compactness  and  ease  of 
reference,  this  gives  a  table  for  all  conversions  needed,  while  previously 
there  has  been  published  no  single  table  that  will  convert  barometrical 
observations  at  the  highest  stations,  e.  g.  Pike's  Peak. 

3.  Only  one  table  is  given  for  each  computation.      For  barometric 
hypsometry,  in  place  of  Guy  of  s  seven  tables  in  both  English  and  French 
measures,  only  one  is  given  in  each,  the  best  and  most  convenient,  as  found 
by  six  year's  constant  use  of  various  tables. 

4.  Only  tables  needed  for  current  meteorological  work  are  included. 

JA11  references  to  Guyot  are  to  4th  ed.,  Wash.,  1884. 


TEMPERATURE    TABLES.  IV 

Thus,  tables  for  converting  Beaumur  temperatures,  Eussian  half  lines,  etc., 
are  omitted,  because  needed  to-day  only  for  the  reduction  of  old  observa- 
tions, and  this  rare  use  can  well  be  supplied  by  Guyot. 

5.  The  latest  determination  of  the  metre  is  used  in  all  linear  tables. 
The  old  length  of  the  metre,  39.37079  in.,  has  been  used  thus  far,  in  all 
tables  in  this  country  and  abroad,  the  usual  argument  being  the  inadvisa- 
bility  of  a  change  previous  to  an  authoritative  determination.     But  the 
length  of  the  metre  is  now  known  so  closely  that  the  outstanding  correc- 
tion can  affect  none  of  the  values  in  our  tablgs,  while  the  old  length,  when 
the  tables  are  carried  to  .001  in.  (p25  mm4/introduces  afoaoorly  oonotant 

A 

error  of  .001  in.  The  length  adopted  is  39.3702  in.,  for  which  determination 
I  am  indebted  to  Professor  W."  A.  Eogers,  of  Bowdoin  College,  who  is  .con- 
fident that  the  true  value  lies  between  39.37015  and  39.3702  in.  An  error  of 
.0001  is  hardly  possible,  and  as  the  change  of  .0006  from  the  old  value 
makes  a  change  of  only  .001  in.  in  the  conversion,  it  is  clear  that  any  pos- 
sible outstanding  error  is  far  within  the  tabular  values.  A  table  computed 
on  the  new  length  will  require  no  modification  in  the  future. 

6.  Several  new  tables  are  introduced.     At  the  head  of  each  table,  or 
in  its  introduction,  the  authority  is  stated.     If  the  table  be  new,  i.  e., 
recomputed  or  never  before  published  in  this  form,  it  is  marked  ("Orig- 
inal ");  if  copied  or  enlarged  from  Guyot  or  any  other  author,  the  source 

/  . 
is  given. 

7.  At  the  end  of  the  volume  are  given  plates  showing  the  distribution 
of  the  more  important  meteorological  elements  for  the  United  States. 

I  gratefully  acknowledge  the  great  assistance  rendered  me  by  Mr.  C.  J. 
Sawyer  in  the  final  arrangement  of  the  hand-book.

TABLES  X  TO  XIV. 

BAROMETRIC   HYPSOMETRY  AND  REDUCTION  TO  SEA-LEVEL, 

INTRODUCTION, 


BAROMETRIC  HYPSOMETRY. 

Many  formulae  and  tables  have  been  devised  for  computing  heights 
from  barometric  observations,  and,  conversely,  for  reducing  barometer 
readings  to  sea-level,  but  nearly  all  are  based  on  the  formula  of  Laplace, 
published  in  1805.  * 

The  complete  formula  includes  a  term  dependent  on  the  hygrometric 
conditions  of  the  air  column,  but  the  use  of  this  term  is  unsatisfactory, 
since  we  do  not  know  the  exact  vertical  distribution  of  moisture.  More- 
over, experience  seems  to  indicate  that  this  term  will  often  introduce  an 
error.  For  example,  in  the  case  of  Mt.  Washington,  the  full  formula,  as 
developed  by  Professor  Ferrel,  gives  a  height  of  6,326  feet,  computed  from 
the  mean  of  several  years'  observations,  while  the  true  height  is  6,279  feet; 
of  this  error  of  47  feet,  at  least  20  feet  is  due  to  the  use  of  a  term  depending 
on  the  moisture.  This  term  was  ignored  by  Professor  Guyot,  and  the  Inter- 
national Meteorological  Committee  has  recently  decided  to  omit  it  in  their 
tables,  about  to  be  issued. 

The  formula  selected  for  the  English  tables  was  that  of  Professor 
Ferrel;2  the  form  of  table  is  that  of  Angot,3  which  has  been  found  by  far  the 
most  concise  and  convenient  yet  devised.  The  formula  is: 

30 

H  =  60521  (1  +  .001017)  X  36  X  log.  —  +  H'  \  1  -f  .001017  (f  +  t  —  100) 

P  ( 

H     (1  +  .002606  Cos.  2  <J>).

VIII— XVI.       PRESSURE    TABLES. 

The  three  tables  for  the  different  parts  of  the  formula  need  no  explana- 
tion. 

EXAMPLE. 

Mt.  Washington,  P  =  23  .61  :  t  =  25° 

Base P  =     29.97  :  t'  —  45° 

$  =  44°  16' 

From  Part  1,  argument  23.61,  we  have 6526

METEICAL. 

For  the  metrical  tables,  those  of  Angot  are  copied,  with  the  single 
omission  of  the  part  relating  to  the  moisture  contents  of  the  air  column. 

REDUCTION  TO  SEA-LEVEL. 

The  above  remarks  relative  to  vapor  pressure  apply  as  well  to  these 
tables.  A  strict  application  of  the  formula  requires  a  correction  for  the 
observed  pressure,  but  experience  has  shown  that,  assuming  the  mean 
temperature  of  the  air  column  to  be  the  mean  of  that  at  the  base  and 
summit,  the  correction  for  observed  pressure  vanishes.1 

If  a  gravity  correction  be  desired,  it  may  readily  be  found  by  Table 
XIV.  In  practice,  it  will  be  best  to  draw  up  a  table  for  the  single  eleva- 
tion of  the  station,  and  for  each  two  degrees,  if  the  height  be  above  1,000 
feet.  The  temperature  to  be  used  is  an  approximate  mean  for  the  previous 
24  hours.  If  observations  are  made  at  equal  intervals  three  times  each 
day,  the  mean  of  the  three,  including  the  current  observation,  is  to  be 
taken. 

The  metrical  tables  are  computed  in  the  same  manner  as  the  English.

In  this  table  the  column  headed  mts.  presents  the  mean  of  a  very  large  number  of  observa- 
tions collated  by  Dr.  Hann,  and  the  same  is  true  of  the  column  headed  balloons,  Hann.    These 
were  from  unventilated  psychrometers. 
The  second  and  third  columns  under  "  balloons  "  are  the  results  with  a  sling  psychrometer  in 
balloon  voyages  on  June  17,  1887,  at  St.  Louis,  and  on  August  13,  at  Philadelphia.    The  results  in 
the  latter  cases  were  very  satisfactory,  agreeing  at  the  same  height  in  the  ascent  and  descent.

TABLES  XX  AND  XXI. 


WEIGHT  OF  VAPOR. 


INTKODUCTION. 

It  is  often  necessary  to  determine  the  weight  of  vapor  in  air  having 
various  percentages  of  humidity.  The  simplest  method  is  based  on  the 
principle  that  the  quantity  of  vapor  is  constant  at  any  given  dew-point, 
whatever  may  be  the  relative  humidity  of  the  air.  Hence,  the  dew-point 
being  given,  we  may  immediately  obtain  the  weight  of  vapor  by  these 
tables.  The  dew-point,  if  not  given,  may  be  found  from  the  wet  and  dry 
bulb  temperatures  by  Table  XXII  or  XXIII. 

EXAMPLE. 

Let  the  air  temperature  be  55°,  and  the  wet  bulb  temperature  44°. 
From  Table  XXII,  we  find  the  dew-point  30°,  and  from  Table  xfe,  with  dew- 
point  30°,  the  weight  of  vapor  is  1.969  gr.

XVII-XXIII.       HUMIDITY    TABLES. 


TABLES  XXII  AND  XXHI. 


DEW-POINT  AND  RELATIVE  HUMIDITY. 


INTRODUCTION. 

For  nearly  one  hundred  years,  a  convenient  method  of  determining  the 
moisture  contents  of  the  air  from  readings  of  the  wet  and  dry  bulb  ther- 
mometers has  been  sought.  The  main  difficulty  in  all  discussions  has  been 
the  lack  of  ventilation  of  the  wet  bulb.  The  simplest  form  of  expression 
is  that  of  Regnault1  as  follows: 

x  =  f  —  a  (t  —  t ')  p.,    in  which, 

x  =  the  vapor  pressure  at  the  dew-point; 

/  =  the  vapor  pressure  at  the  wet  bulb  temperature; 

t  =  the  observed  (C.)  temperature  of  the  air; 

V  =  the  observed  (C.)  temperature  of  the  wet  bulb; 

p  =  the  pressure  of  the  air; 

a  =  a  constant  to  be  determined  by  experiment. 

The  value  of  a,  as  determined  by  different  experimenters,  has  ranged 
from  .00084  to  .00067.  The  larger  value  from  un ventilated  readings,  and 
the  smaller  by  means  of  the  sling  psychrometer. 

A  long  series  of  experiments  by  the  author2  has  shown  that  the  latter 
value  is  satisfactory.  Assuming 

p  =  29.4  and,  a  =  .000673, 
the  formula  becomes 

x=f—.011(t  —  t/), 

which  is  easy  for  computation  in  English  measures. 

The  above  formula  has  received  a  marked  confirmation  by  the  experi- 
ments of  Dr.  A.  Sprung  with  an  Assman  aspiration  psychrometer.  The 
results  are  given  in  "  Das  Wetter,"  Vol.  V,  p.  105,  and  show  the  same  value 
of  the  constant  adopted  here.  We  may  feel  assured  that  this  formula  is

XVII-XXIII.       HUMIDITY    TABLES. 

exact,  and  the  table  may  be  used  for  all  properly  ventilated  psychrom- 
eters. 

The  following  formula  has  been  deduced  by  Professor  Ferrel  from  a 
long  series  of  observations  with  the  sling  psychrometer  at  Colorado  Springs 
and  Pike's  Peak  by  Professor  Marvin: 

x  =  f-  .000367  (t-n  p    1 


The  temperature  is  in  (F.)  degrees.     Substituting, 

p  =  29.4,  we  have,  for  t  —  t'=  10°,  x=f—  .011  (t  —  V\ 

which  agrees  with  the  above  formula  in  all  cases  except  when  the  air  is  very 
dry,  and  even  then  the  difference  seldom  amounts  to  1°  in  the  computed 
dew-point,  which  is  far  within  the  accuracy  of  vapor  pressures  used. 

While  these  tables  apply  strictly  only  to  sling  or  ventilated  psychrom- 
eters,  yet  they  will  be  but  slightly  in  error  for  all  shelters  of  fair  exposure. 

Kegnault's  original  formula  contained  a  slight  modification  for  readings 
of  the  wet  bulb  when  covered  with  ice,  based  on  a  theoretical  difference  in 
evaporation.  Experiment,  however,  has  shown  that  there  is  no  difference  in 
the  results,  whether  the  bulb  be  covered  with  ice  or  water,  and  no  change 
has  been  introduced  in  these  tables. 

The  tables  have  been  computed  for  a  constant  barometer  reading  of 
29.4  in.,  as  the  average  air-pressure  at  the  majority  of  stations  in  this  coun- 
try. It  will  be  found  that,  up  to  3000  feet  the  errors  incident  to  the  use  of 
the  psychrometer  are  much  greater  than  will  justify  a  correction  for  press- 
ures differing  from  29.4  in.,  but  either  Part  II  or  III  of  the  table  will  enable 
one  to  apply  this  refinement,  if  desired. 

It  will  readily  be  seen,  from  the  construction  of  the  table,  that,  if  there 
be  given  the  dew-point  from  Eegnault's  condensing  hygrometer,  and  the 
air-temperature,  the  relative  humidity  may  be  deduced  without  difficulty. 

EXAMPLES. 

Given,  t  =  65°;  t'  =  50°;  then  t  —  t'=  15. 

From  Table  XXII,  with  the  above  values,  we  find;  dew-point  =  34°,  and 
relative  humidity  =  31  per  cent. 

Given,  t  =  65°,  t'  =  55°,  p  =  26". 
Table  XXII  gives  dew-point  47°. 

57 


XVII-XXIII.       HUMIDITY    TABLES.  *, 

From  Table  XVII,  the  vapor  pressure  for  dew-point  47°  =  .322;  the  cor- 
rection of  this  from  Table  XXII,  Part  II,  f or  i  —  t'  =  10°  and  p  =  26"  is 
-h  .013.  Table  XVII,  with  vapor  pressure  =  .335  gives  dew-point  =  48°. 
Table  XXII,  with  air-temperature  =  65°  and  dew-point  =  48°,  gives  relative 
humidity  =  54  per  cent.  This  correction  to  the  dew-point  for  pressure,  may 
be  found  much  more  readily  from  Table  XXII,  Part  III,  as  follows: 
Given,  t  =  65°,  t1  =  55°, p  =  26". 

The  dew-point  =  47°,  as  before;  Part  III,  with  air-temperature  —  65°, 
pressure  =  26",  and  t  —  tr  =  10°,  gives  correction  =  1°;  hence,  dew-point 
corrected  for  pressure  =  48 D,  as  before. 

RELATIVE  HUMIDITY   FROM    CONDENSING   HYGROMETER. 

Given,  t  =  65°;  dew-point  =  40°;  we  have  at  once,  relative  humidity  =  39  per  cent. 
While  these  tables  are  extended  to  — 40°  F.  and  below  for  the  dew- 
point,  yet  it  should  be  borne  in  mind  that  we  have  no  experimental  vapor 
tensions  below  —  22°  F.,  but  the  tables  are  computed  on  extrapolated  values 
from  the  formulae.  A  series  of  experiments  in  the  Northwest  in  winter 
extending  Eegnault's  work  20  or  30  degrees  lower  would  be  of  great  value.

XXIV  TO  XXX -WIND  TABLES. 


TABLE  XXIV. 

LAMBERT'S    FORMULA   FOR   THE   DETERMINATION    OF   MEAN   WIND 

DIRECTION. 


INTRODUCTION. 
Lambert's  formula  for  the  8  principal  wind  directions  is  as  follows: 

Tan  A  _  E.  —  W.  -f-  (N.E.  —  S.W.)  cos.  45°  +  (S.E.  —  K.W.)  cos.  45° 

N".  — S.+  CST.E.  —  S.W.)  cos.  45°  —  (S.E.  —  K.W.)  cos.  45° 

in  which  N.,  N.  E.,  etc.,  represent  the  number  of  times  the  wind  has  blown 
in  each  octant  during  the  period  under  consideration.  We  assume  that  the 
wind  velocity  is  the  same  from  all  points.  If  directions  from  16  points  are 
observed,  half  of  each  extra  point  should  be  added  to  the  direction  preceding 
and  following;  for  example,  with  N.  N.  E.  6,  N.  E.  5,  E.  N.  E.  3,  E.  2,  E.  S.  E. 
4,  we  would  enter  the  formula  with  N.  E.  9.5,  E.  5.5,  etc.  The  result  will 
be  almost  identical  with  that  from  the  full  formula  of  16  points. 

The  table  is  in  two  parts:  part  I  gives  the  product  of  any  number  with 
cos.  45°  (.7071),  and  part  II  the  value  of  the  angle  or  its  complement,  in 
degrees.  For  the  computations,  the  following  form  should  be  used: 

abcdefghik         1         m       n       opqrs    part  II  angle 

E  W  N  SNE  SW  SE  NW  e-f  g-h  i  cos.  45  kcos.45  a-b  1+m  c-d  1-m  o-fn  p+q     — 

f^        (  S 

212202^13      9*      0       10       4       -10         2.8         -7.1      -10     -4.3      -5     9.9   -14.3    4.9      19°         N.  71  W. 

r 

The  signs  of  —  give  the  quadrant, 
s 


r         s 

If  the  fraction  —  or  —  is  not  less  than  j$$,  divide  both  numerator  and 
s          r 

denominator  by  any  number  till  the  values  of  r  and  s  are  found  within 
part  II.  Always  enter  part  II  with  the  smaller  number  as  the  horizontal 
argument.  If  s  be  smaller  than  r,  take  the  complement  of  the  angle,  as 
found  in  the  table. 

74 


XXIV-XXX.       WIND    TABLES. 


In  the  use  of  this  table  it  will  be  found  that  the  larger  the  figures,  pro- 
vided they  are  under  iH,  the  easier  the  computation.     For  example,  sup- 

r        -18 

pose  —  — .     In  the  table  there  is  no   18  opposite   14,  but  if  we 

s         14 
multiply  the  fraction  by  5  we  have  U,  and  the  corresponding  angle  from 

part  II  is  38°,  or  taking  the  complement,  since  s  is  less  than  r,  we  have 
N.  52°  W.     The  same  result  is  attained  if  we  multiply  by  10.

TABLE  XXVII. 


CONVERSION   OF  WIND   VELOCITY   IN   MILES   PER   HOUR  TO  PRESSURE 
IN  POUNDS  PER  SQUARE  FOOT. 


INTRODUCTION. 

In  many  investigations  it  is  necessary  to  express  the  velocity  of  the 
wind  in  terms  of  the  pressure,  but  the  determination  of  this  relation  is 
difficult,  and  the  problem  has  attracted  the  attention  of  physicists  for  a 
hundred  years. 

Of  the  various  results,  those  of  Bouse,  quoted  by  Smeaton1  seem  most 
consistent  with  recent  investigations2.  The  formula,  as  announced  by 
Smeaton  from  Rouse's  experiments,  is: 

p  =  .005  v*  .s,    in  which 

p  =  the  pressure  in  pounds; 

v  =  the  velocity  in  miles  per  hour; 

s  =  the  surface  in  square  feet. 

The  table  has  been  computed  from  this  formula,  s  being  taken  as  one 
square  foot. 

It  will  be  understood  that  the  table  is  strictly  applicable  only  to  sur- 
faces of  about  one  square  foot,  and  for  velocities  from  twenty  to  forty 
miles  per  hour.

EXAMPLE. 

To  Find  Local  Time  of  Greenwich  Noon  in  Longitude  49°  26'  West  of  Greenwich. 
Look  for  degree  of  longitude  49  and  we  find  8  A.  M  at  the  head.    26'  of  longitude 
in  the  center  table  gives  opposite  49°:  42™ ;  hence  local  time  of  Greenwich  noon  in 
longitude  49°  26'  W.  is  8:42  A.  M. 

To  Find  Greemvich  Time  of  Local  Noon  in  Longitude  95°  40'  W. 

Greenwich  noon  =  5:37  A.  M.  Subtract  5:37  from  12,  and  we  have  6:23  p.  M., 
Greenwich  time  of  local  noon. 

To  Find  Local  Time  of  Any  Greemvich  Time. 

Find  2:35  p.  M.  Greenwich  time  in  longitude  111°  35'  W.  Greenwich  noon  —  4:34 
A.  M.  local  time.  2:35  p.  M.  Greenwich  time  would  be  2  hours  35  minutes  later,  or 

7:9  A.  M.  local  time. 

To  Find  Greenwich  Time  of  Any  Local  Time. 

Find  Greenwich  time  of  4:37  P.  M.  local  time  in  98°  8'  longitude  W.  Local  time 
of  Greenwich  noon  =  5:27  A.  M.;  4:37  p.  M.  is  11  hours  10  minutes  later,  or  11:10  p.  M^ 
Greenwich  time. 

To  use  this  table  for  any  other  meridian  than  Greenwich,  substitute  for 
"Greenwich  noon"  its  time  at  the  meridian  desired. 

Given  7  A.  M.  Eastern  Time,  to  find  its  Local  Time  in  Longitude  112°  48'  W. 
Over  112  we  find  4,  and  opposite  that  for  45'  we  have  29.    Hence  7  A.  M.  (Eastern) 
=  4:29  A.  M.  (local)  in  longitude  112°  48'  W.

XXXVII-XLV.       MISCELLANEOUS    TABLES. 


TABLE  XL. 
TO  DETERMINE  THE  POSITION  OF  A  POINT  ON  A  MAP. 

INTRODUCTION. 

This  table  is  designed  to  facilitate  the  determination  to  minutes  of  arc, 
of  positions  on  a  map  with  lines  of  latitude  and  longitude,  having  given  the 
shortest  distances  on  the  map  from  the  point  to  the  nearest  parallel  and 
meridian.  For  use,  first  measure  on  any  convenient  scale  the  distance 
between  any  two  lines  of  latitude  or  longitude.  If  no  figure  at  the  top  of 
the  table  coincides  with  this  distance,  it  may  be  multiplied  or  divided  by 
any  number  to  bring  it  within  the  range  of  the  table.  Then  measure  the 
distance  on  the~same  scale  from  the  point  to  the  line  of  latitude  or  longi- 
tude and  find  the"same  number  multiplied  or  divided  as  above,  if  necessary, 
in  the  left-hand  column.  The  intersection  of  lines  from  these  two  numbers 
will  give  the  minutes^of  latitude  or  longitude  on  the  map. 

EXAMPLE. 

Let  distance  between  two  meridians  be  46  mm-,  and  that  from  a  point  to  the 
nearest  meridian  20mm-;  the  minutes  of  longitude  are  26.

XXXVII-XLV.       MISCELLANEOUS    TABLES. 


TABLES  XLI-XLIII. 

DIVISION   TABLES. 


INTEODUCTION. 

These  tables  are  designed  to  facilitate  division  by  28,  29  and  31 :  divisors 
of  frequent  use  in  meteorological  reductions. 

The  horizontal  rows  of  figures  lettered  "D"  in  plain  and  bold-faced 
type  are  respectively  the  first  three  and  last  two  figures  of  the  dividend. 
The  corresponding  numbers  in  the  horizontal  rows  lettered  "  Q  "  are  respect- 
ively the  hundreds,  tens  and  units  figures  of  the  quotient. 

EXAMPLE.      TABLE  XL^" 

To  divide  22883  by  28: 

Under  228  in  the  horizontal  rows  (D)  we  find  8,  and  under  76,  the  number  nearest 
to  83,  in  bold-faced  type,  we  find  17. 
Hence  the  quotient  is  817^V.
